Wave Reflection and Behavior Quiz

What is a standing waveform?

• A single wave pulse

• Multiple waves in succession

• A wave that does not move

• A wave that changes medium

What happens to a straight plane wave when it reflects off a straight barrier?

• It becomes a curved wave

• It reflects as a straight plane wave

• It changes speed

• It changes frequency

Why does the speed of a wave remain constant when reflecting off a barrier?

• Because it reflects at an angle

• Because it changes medium

• Because it does not change medium

• Because it changes frequency

What is the formula used to calculate wave speed, distance, and time?

• Speed = Distance * Time

• Speed = Time / Distance

• Speed = Distance / Time

• Speed = 2 * Distance / Time

In the echo formula, what does the 'distance' refer to?

• Distance the wave travels in the medium

• Distance the wave travels in one second

• Distance between the wave source and the barrier

• Distance between two wave crests

What is a practical application of wave reflection technology?

• Sonar in submarines

• Changing wave frequency

• Reducing wave amplitude

• Increasing wave speed

What is the angle of incidence?

• The angle between two waves

• The angle between the wave and a perpendicular line to the barrier

• The angle between the wave and the ground

• The angle between the wave and the barrier

What is true about the angle of incidence and the angle of reflection?

• They depend on the wave speed

• They are equal in all cases

• They depend on the wave frequency

• They are always different

What happens to waves when they reflect off a concave barrier?

• They change speed

• They diverge

• They converge at a focal point

• They become straight

How do waves behave when reflecting off a convex barrier?

• They diverge

• They remain straight

• They converge

• They change frequency
